Dear all, I know that faafo ( https://opendev.org/openstack/faafo ) is no longer being maintained, but I still use it to present some service deployment in my teaching about cloud systems. The application still runs nicely in Ubuntu1804, but I tried to configure the RabbitMQ queue to be created in the publisher (Service API), instead of in the consumers (Service Worker), but I failed. My intention was to show that messages could be published in the queue without any workers having been deployed yet. I thought adding a "maybe_declare" statement in the publisher "would do the trick": https://github.com/jmaransay/faafo/blob/478428f11d92cc22d1be396afec3c787136d... But still the message queue is only created when the first worker machine is deployed. Does anybody still have some clue about why the application was configured like that, or how the queue could be created in the publisher? Any hints would be highly appreciated, thank you very much in advance, Jesús -- Jesús María Aransay Azofra Universidad de La Rioja Dpto. de Matemáticas y Computación tlf.: (+34) 941299438 fax: (+34) 941299460 mail: jesus-maria.aransay@unirioja.es web: http://www.unirioja.es/cu/jearansa Edificio Científico Tecnológico-CCT, c/ Madre de Dios, 53 26006, Logroño, España
